32-bit Package

This package type can be installed on both 32-bit and 64-bit platforms. It is recommended to use this package type if your application contains no 64-bit binaries and you don't want to interact with any 64-bit folder or registry location.

64-bit Package

A 64-bit package (both Intel64 and x64) is meant to install files in 64-bit folder locations and/or entries in 64-bit registry portion.

ImportantA 64-bit package can't be installed on 32-bit platforms.

AI_ProgramFiles---C:\Program Files\C:\Program Files\

Paths to system folders are retrieved differently on 64-bit platforms than on 32-bit platforms. In a 64-bit package you can use the following folders:

ProgramFiles64Folder - C:\Program Files\
CommonFiles64Folder  - C:\Program Files\Common Files\
System64Folder       - C:\Windows\system32\

Their 32-bit counterparts are resolved to redirected locations as follows:

ProgramFilesFolder - C:\Program Files (x86)\
CommonFilesFolder  - C:\Program Files (x86)\Common Files\
SystemFolder       - C:\Windows\SysWOW64\

NoteAlthough 32-bit package can be installed on 64-bit platforms, the ProgramFiles64Folder, CommonFiles64Folder and System64Folder are resolved to the redirected locations, that is why you need a 64-bit package in order to access the real system paths on a 64-bit platform.

Mixed 32/64-bit matching the platform

This package runs as a 32-bit package on 32-bit systems and as a 64-bit package on x64 systems. It allows you to have a single installation package that will install on both platform types (32-bit and 64-bit platforms) and can install files or registry in the real system paths regardless of the platform.

Since “ProgramFilesFolder” property is resolved to redirected location on 64-bit platforms, and “ProgramFiles64Folder” is not defined on 32-bit platforms, for this kind of packages, Advanced Installer defines the “AI_ProgramFiles” property that will point to the system program files (C:\Program Files\) on both platform types.
